Multi-signature method, computer equipment and storage medium

Abstract

The invention provides a multi-signature method, computer equipment and a storage medium. The method comprises the following steps: executing a multi-signature contract initialization transaction, and configuring a signature number threshold value required by verification after the verification of an initialization authority succeeds, and the information of each account with the multi-signature authority; an asset storage transaction is executed, and the first asset is stored in the first contract address; executing a multi-signature asset extraction transaction: generating a first hash value according to the asset receiving address, the amount of the second assets requested to be extracted and the historical asset extraction times of the contract; according to the account information with the multiple signature permissions, the number of accounts with the multiple signature permissions signed for the first hash value and included in the transaction is determined; and judging whether the number is not less than a signature number threshold, and if so, transferring the second asset from the first contract address to the asset receiving address. According to the invention, the service charge of the user and the resources of the block chain system are saved, and the efficiency of multi-signature verification is improved.

Description

technical field [0001] This application relates to the technical field of block chain, and specifically relates to a multi-signature method, computer equipment and storage media. Background technique [0002] In existing blockchain systems, multi-signature schemes require users with signature authority to send transactions separately for authorization. [0003] For example, if a multi-signature account is configured with 6 users A-F with signature authority, it is required that at least 4 of the user signatures can pass the multi-signature verification. [0004] When the multi-signature account wants to pay an asset: [0005] User A signs and generates an authorized transaction txA and sends it to the blockchain network; after the multi-signature contract executes txA successfully, record the authorization of user A in the contract, and judge whether the number of authorized users (1) is not less than 4: if not, the payment will not be executed operate. [0006] User C si...

AI Technical Summary

Problems solved by technology

[0009] In the above scheme, on the one hand, each multi-signature authorization needs to send multiple transactions, which not only wastes the user's handling fee, but also wastes the system resources of the blockchain;

[0010] On the other hand, for some business scenarios that require efficient multi-signature verification, the efficiency of the above scheme is low, and there are many uncertain factors

For example, the account balance of one of the authorized users is not enough to pay the transaction fee of the authorized transaction, resulting in delays in passing multi-signature verification, etc.
